Hot Reload doesn't work in linux

[lesinlor]

I run init npm i and npm run dev ,the hot reload doesn't work even i reload the website.Only i reload the server that will reload what i change in the code.
After i changed some codes in build/dev-server.js,hot reload run(line 26):

var devMiddleware = require('webpack-dev-middleware')(compiler, {
  publicPath: webpackConfig.output.publicPath,
  quiet: false,
  stats: {
    colors: true,
    chunks: false
  },
  watchOptions: { //Add Polling
    aggregateTimeout: 300,
    poll: 1000
  }
})

thanks

I think you should post this on the webpack template issue tracker => https://github.com/vuejs-templates/webpack/issues
